What is the 1-MB I/O performance of Azure Virtual HD on Windows 10 as the application drive "D:"?

The I/O performance of reading and writing 1-MB files of a Azure Virtual HD on Windows 10 as the application drive "D:" can be measured by running SQLIO with multiple 1024-KB blocks with a large stripe factor.

Here is the read performance test of Azure Virtual HD on Windows 10 as the application drive "D:" with 1024-KB blocks.

D:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s30 -p0

using system counter for latency timings, 10000000 counts per second
